AH500 Hardware Manual
5.2.2 Ground
 The diameter of the ground should not
be less than the diameters of the cables
connected to the terminals L and N.
 If much equipment is used, please use
single-point ground.
AHPS05-5A Other equipment
The single-point ground is better.
 If single-point ground can not be used,
please use common-point ground.
AHPS05-5A Other equipment
The common-point ground is permitted.
 Users can not ground equipment in the
way shown on the right.
AHPS05-5A
Other equipment
The equipment can not be grounded in this way.

*1. The 24 V power supply is connected to VS+ and VS- on the power supply module. VS+ and VS-
can be used to detect whether the voltage of the external power supply is stable.
*2. FG on the power supply module is connected to the control box as the functional ground.
*3. The live cable and the neutral cable are connected to L and N on the power supply module
respectively. To prevent the system from becoming abnormal, the ground has to be connected to
LG on the power supply module.
The power input of AHPS05-5A is the AC input. Users have to pay attention to the following points
when they use AHPS05-5A.
 The alternating-current input voltage is within the range between 100 V AC and 240 V AC.
Please connect the power supply to the terminals L and N. If the 110 V AC or the 220 V AC
power supply is connected to the input terminals VS+ and VS-, the PLC will be damaged.
 In order to ensure that the 24 V DC external power supply is provided stably, it can be
connected to VS+ and VS-. If the PLC detects that the voltage of the external power supply is
lower than the working voltage, users can write a protective program.
